WILLIAM A. DEAN, OF GORNING, NEW YORK.

RAILWAY STRUCTURE.

To all whom it may concern:

Be it known that I, WILLIAM A. DEAN, a citizen of the United States,residing at Corning, in the county of Steuben and State of New York,have invented-certain new and useful Improvements in Railway Structures,of which the following is a specification, reference being had to theaccompanying drawings. I My invention relatesto improvements in railwaystructures, and particularly to impro tements in metallic railwayftiesand ineans for securing the rails thereto.

An gbject of my invention is to provide a structure of the classdescribed which will be simple in construction, comparatively cheap inmanufa -F' re and cfiicient and safe in operation.

In the drawings illustrating the principle of my invention and the bestmode now known to me of applying that principle, Figure 1 is a top planview of my new structure; Fig. 2 is a sectional view on the line AA ofFig. 1; Fig. 3 is an end view of the tie; Fig. 4 is a detail showing inplan the locking plate; Fig. 5 is a detail showing in plan the chair;Fig. 6 is a detail sectional view showing the retaining bolt in place inthe tie; Fig. 7 is a perspectivedetail of the retaining bolt and Fig. 8is a detail showing the location of the slots formed in the end of thetie.

The tie a is preferably made of sheet metal bent into the form bestshown in Fig. 3 and having wing portions b at its mid-portion on eachside which incline from the top downwardly and outwardly (Figs. 1 and3). These wing portions prevent endwise creeping or displacement of thetie a. At eachen-d the tie is formed with two slots 0 and d. The slot 0extends across the tie while the slot d extends in the direction of thelength of the tie. The chair or brace e is shown in Fig. 5 in detail andin Fig. 2 in sectional view. It is provided Specification of LettersPatent. Application filed March 19, 1907.

,a,(Fig. 6). The shank p and the lip u of the locking plate .9.

with a tongue or lip f adapted to pass through the slot 0 and engage theunder side or face of the top of the tie, (Fig. 2). The chair e isfurther formed with ears g adapted to fit snugly over the inclined upperface it of the base of the rail 1'. The latter is seated upon the flatbase portion of the chair 6; and this fiat base portion is formed with akeyhole-shaped slot 1: which is adapted to register with the slot d inthe tie a. The retaining bolt m is formed shoulder 0. The shank p of theretaining bolt an is pushed down through the slot (1 in the tie andturned I through a quarter turn and then drawn back so that the squareshoulder 0 engages the walls of the slot 01,

therebyserving to lock the bolt against rotation; In

with a head n and a'square order to prevent the disengagement of theshoulder o collar or washer q is screwed down upon the shank of d by thebolt falling, the v Patented July 9, 1907. Serial No. 363,304.

the bolt, until the'washer rests upon the top of the tie of the bolt mextends upwardly through the hole 1' in the locking plate s (Figs.

2 andfi) and a nut t is screwed down upon the shank,

until it rests upon the top of securing the latter firmly plate .9 isformed with a lip the base of the rail t'.

the locking plates, thereby in position. The looking it which fits overthe top of From the foregoing it will be seen'that the chair or positionand that the rail t brace f is readily placed in is securely heldbetween the curved lips g of the chair By the arrangement'of the partsjust described and shown in the drawings, the locking plates is readilyand securely placed in position by passing it over the shank p of thebolt m and screwing down the nut t. Thus, the laying of the track isgreatly expedited ,and the whole structure is very compact and secureand cannot be displaced by atwisting or turning of the chair. e.

Details of construction may be varied without departing from the spiritof my invention. Thus, the locking plates s may be both placed upon theinside of the rails, while the braces a may be both placed on theoutside thereof; or vice versa, by merely changing the position of theslots 0 and d, at one end of the rail.

I claim:

1. In a railway structure combination with the rail, of a tie formedwith a slot; 11.

and with cars which engage one side of the base of the rail; and alocking plate secured above said brace and tie and in engagement withthe other side of the base of said rail.

2. In a railway structure of the class described, the combination withthe ral1,'of a. tie formed with a slot; 8.

base of the rail.

3. In a railway structure of the'class described, the combination withthe rail, of a tie formed with a slot; 8. bolt the shank of whichextends through said slot upwardly from beneath the top of said tie,said bolt being formed with a shoulder which engages the walls of saidslot to prevent rotation of the bolt andbeing provided with a collar toprevent said bolts falling through said slot; rail-locking devicesmounted on said tie; and a nut on said shank for holding said devices inplace. v

in testimony whereof I have hereunto set myhand in the presence of thetwo undersigned witnesses.
